announce that the Mackenzie Valley Environmental Impact Review Board
(MVEIRB) has concluded the Gahcho Kue Environmental Impact Assessment
and has recommended approval of the proposed Gahcho Kue diamond mine
subject to measures and follow-up programs.


In a July 19, 2013 letter to the Minister of Aboriginal Affairs and
Northern Development Canada, the Honourable Bernard Valcourt, the
MVEIRB stated: "The Gahcho Kue Panel recommends, pursuant to
sub-section 134(2) of the Mackenzie Valley Resource Management Act,
that this development be allowed to proceed subject to implementation
of the measures and follow-up programs described in this Report which
are necessary to prevent potentially significant adverse impacts on the
environment."


Glen Koropchuk, De Beers Canada Chief Operating Officer, stated: "We are
pleased to receive the Report of Environmental Impact Review and
Reasons for Decision by the Mackenzie Valley Environmental Impact
Review Board on the proposed Gahcho Kue diamond mine. This represents
an important step forward for the proposed new diamond mine. We are
reviewing the Report to better understand the implications of the
measures and follow-up programs recommended by MVEIRB. We look forward
to proceeding to the next stages in the regulatory approval process.


"We want to thank the Panel and staff of the MVEIRB for considering all
of the evidence in preparing the Report. We also appreciate the
continued participation by Aboriginal parties and other community and
regulatory stakeholders as the Gahcho Kue Project moves ahead."


Patrick Evans, Mountain Province Diamonds President and CEO, added: "The
Gahcho Kue joint venture has successfully demonstrated to the Review
Board that the Gahcho Kue diamond mine can be successfully constructed
and operated. Completion of the environmental review is a significant
milestone".
